    </div>

    <p>The STM32CubeL1 Firmware package comes with a rich set of examples running on STMicroelectronics boards, organized by board and provided with preconfigured projects for the main supported toolchains.</p>

    <div class="picture">
      <img alt="" src="../_htmresc/STM32Cube.bmp"/>
    </div>

    <p>The examples are classified depending on the STM32Cube level they apply to, and are named as follows:</p>

    <ul>
      <li id="Examples"><b>Examples</b> uses only the HAL and BSP drivers (Middleware not used), having as objective to demonstrate the product/peripherals features and usage. The examples are organized per peripheral (a folder for each peripheral, ex. TIM) and offers different complexity level from basic usage of a given peripheral (ex. PWM generation using timer) till integration of several peripherals(use DAC for signals generation with synchronization from TIM6 and DMA). Board resources usage is reduced to the strict minimum.</li>
      <li id="Examples_LL"><b>Examples_LL</b> uses only the LL drivers (HAL and Middleware not used), offering optimum implementation of typical use cases of the peripheral features and configuration procedures. The examples are organized per peripheral (a folder for each peripheral, ex. TIM) and runs exclusively on Nucleo board.</li>
      <li id="Examples_MIX"><b>Examples_MIX</b> uses only HAL, BSP and LL drivers (Middleware are not used), having as objective to demonstrate how to use both HAL and LL APIs in the same application, to combine the advantages of both APIs (HAL offers high level and functionalities oriented APIs, with high portability level and hide product or IPs complexity to end user. While LL offers low level APIs at registers level with better optimization). The examples are organized per peripheral (a folder for each peripheral, ex. TIM) and runs exclusively on Nucleo board.</li>
      <li id="Applications"><b>Applications</b> intends to demonstrate the product performance and how to use the different Middleware stacks available. The Applications are organized per Middleware (a folder for each Middleware, ex. USB Host) or product feature that need high level firmware bricks (ex. Audio). Integration Applications that use several Middleware stacks are provided as well.</li>
      <li id="Demonstrations"><b>Demonstrations</b> aims to integrate and run the maximum of peripherals and Middleware stacks to showcase the product features and performance.</li>
      <li>A Template project is provided to allow user to quickly build any firmware application on a given board.</li>
    </ul>

    <p>The examples are located under STM32Cube_FW_STM32CubeL1_VX.Y.Z\Projects\, and all of them have the same structure:</p>

    <ul>
      <li>\Inc folder that contains all header files.</li>
      <li>\Src folder for the sources code.</li>
      <li>\EWARM, \MDK-ARM and \SW4STM32 folders contain the preconfigured project for each toolchain.</li>
      <li>readme.txt describing the example behavior and the environment required to run the example.</li>
    </ul>

    <p>To run the example, you have to do the following:</p>

    <ul>
      <li>Open the example using your preferred toolchain.</li>
      <li>Rebuild all files and load the image into target memory.</li>
      <li>Run the example by following the readme.txt instructions.</li>
      <li>
        <i><u>Note</u>: refer to section "Development Toolchains and Compilers" and "Supported Devices and EVAL boards" of the Firmware package release notes to know about the SW/HW environment used for the Firmware development and validation. The correct operation of the provided examples is not guaranteed on some environments, for example when using different compiler or board versions.</i>
      </li>
    </ul>

    <p>The provided examples can be tailored to run on any compatible hardware; user simply need to update the BSP drivers for his board, if it has the same hardware functions (LED, LCD display, pushbuttons...etc.). The BSP is based on a modular architecture that allows it to be ported easily to any hardware by just implementing the low level routines.</p>

    <p>The table below contains the list of examples provided within STM32CubeL1 Firmware package.</p>
